It is to be understood that the marking apparatus 100 is applicable toany marking or punching use.

Force Bar with Positioning Member

FIG. 1 shows perspective view marking apparatus 100 with force bar 300and handle (handle 200 can be the length of arm 300 following angle370), and positioning member 500.

In this embodiment positioning member 500 can include marking point 550on bottom side and rounded positioning member on top 520, withpositioning member 500 having two longitudinal grooves (600, 610) andthreads 515 close to marking point 550.

FIG. 1A shows a view taken from the lines A-A of FIG. 1 of the markingpoint 550 of positioning member 500.

FIG. 1B is a perspective view of positioning member 500 wherepositioning member 500 has been rotated 90 degrees relative to theposition shown in FIG. 1. Positioning member is shown rotated to betterillustrate the double grooves 600 and 610 (which can be seen in FIG. 1A,but not in FIG. 1). In FIG. 1B neither groove (600 or 610) lines up withnotch 360 of arm 300. However, preferably during use either groove 600or 610 will be lined up with notch 360 (as shown if FIGS. 1 and 1A).

In one embodiment marking device 100 can comprises a handle 200 (handle200 can be the length of arm 300 following angle 370), arm 300,positioning member 500, and marking point 550. In embodiment positioningmember 500 can be detachably connectable to arm 300.

In one embodiment marking point 550 can include a releasable markingsubstance such as paint, ink, dye, lead, graphite, and/or wax toincrease the visibility of the mark left by marking point 550. In oneembodiment marking point 550 can be similar to the point of a ball pointink pen, or a felt tip pen.

Arm 300 can include first end 310 and second end 320. Positioning 500member can be detachably connected to second end 320. In a preferredembodiment positioning member 500 and marking point 550 can belongitudinally aligned with each other (and can be constructed from asingle material).

Although not shown in the drawings, handle 200 can be non-parallel toand pivotally attached to first end 310.

On second end 320 of arm 300 can be opening 350 which can includesthreaded area 355. In one embodiment opening 350 can include notch 360.First and second ends 310, 320 of arm 300 can be rounded, flat, orangled.

Arm 300 (although illustrated as being generally rectangular) can bemade in other shapes such as rounded, triangular, or other geometriccross sections which provide sufficient strength for the type of usecontemplated, and can fit between the gap of a door and door jam.

Positioning member 500 can include first end 510, second end 520, andhave a length “L”. In a preferred embodiment first end 510 can berounded, hemispherically shaped, curved, and/or pointed to allow foreasy insertion into an opening. Second end 520 can include a pointedarea 550 which can act as punch 700. In a preferred embodiment,positioning member 500 is symmetrically shaped with pointed area 550being located in the longitudinal center line 555.

In one embodiment positioning member 500 can include threaded area 515which threadably attaches to a threaded area 355 (of opening 350) of arm300.

In various embodiments positioning member 500 can be attached to arm 300by threading, wedging, or other attachment techniques. By makingpositioning member 500 detachably connectable to arm 300, it is possibleto replace positioning member 500 easily as this is the primary point ofwear on apparatus 100.

Positioning Member Itself without and with Pull Cord

FIG. 2 shows perspective view of positioning member 500 with markingpoint 550. FIG. 3 shows perspective view of positioning member 500 withmarking point 550 and force application member 900.

In one embodiment positioning member 500 can include one or morelongitudinal grooves 600, 610, and/or 620 (although groove 620 is notshown in the drawings) about its positioning surface 530. In oneembodiment one groove 600 is provided. In one embodiment two grooves 600and 610 are provided which are symmetrically spaced apart 180 degreesfrom each other. Although not shown in the drawings, in one embodimentthree grooves 600, 610, and 620 are provided which are symmetricallyspaced apart 120 degrees from each other.

FIG. 1A is a view of one embodiment of a positioning member 500 withmarking point 550, with the positioning member having two longitudinalgrooves 600 and 610 symmetrically spaced apart (180 degrees from eachother). Grooves 600 and 610 allow for increased adjustability of markingpoint 550 related to top 302 of arm 300 as only one groove need be linedup with notch 360. With only single groove 600 positioning member 550must be turned at least 360 degrees before groove 600 will line up withnotch 360. With two vertical slots 600 and 610 positioning member 550need only be turned 180 degrees before one of the two notched line upwith groove 360. FIGS. 1, 1A, and 1B show relative positions of grooves600 and 610 to notch 360.

Alarm Sensor Installation

The use of apparatus 100 for installing door alarm sensors isschematically illustrated in FIGS. 3-10.

FIG. 4 shows marking apparatus 100 with handle 300 being placed in alarmsensor hole 2020 of top door frame 2010 with alarm sensor wire 20hanging down, and with door 2500 open. The header of door frame 2100 canhave opening 2020 in the header which had been previously made (such asby a drill) a sensor wire 20 hanging from the opening 2020. Although notshown, header can have both a front and rear portion with a door jamtowards the rear and weather stripping placed on the door jam.

Door frame 2000 can have a door sensor system 10 which includes contactwire 20 along with upper 12 and lower sensor 14 elements. Door sensorsystem 10 (which includes upper sensor 12 and sensor wire 20) can beinstalled in the upper portion of a door frame 2000 (see FIG. 10).

In FIG. 4 the sensor wire 20 has been placed in the groove 600 ofpositioning member 500 of apparatus 100. The vertical groove 600 andwire 20 face the rear of the door frame 2000. Positioning member 500 ispreferably about the same size as the opening 2020 in the header 2010.

FIG. 5 shows positioning member 500 of marking apparatus 100 now placedin alarm sensor hole 2020 with alarm sensor wire 20 hanging down, andwith door 2500 open. After positioning member 500 is placed in opening2020 of header 2010, wire 20 still hangs down from opening 2020 but islocated towards the rear of the header 2010 (schematically indicated bythe arrow 21). Marking point 550 is now located about in thelongitudinal center of opening 2020 for header 2010.

FIG. 6 shows door 2500 in closed state and force (schematicallyindicated by arrow 2070) being applied on marking apparatus 100 withhandle 300 while positioning member 500 is in hole 2020 of top doorframe 2010 with alarm sensor wire 20 hanging down on other side of door2500, and with door 2500 closed. Arm is located in gap 2050 between door2500 and frame 2010. Preferably door 2500 is closed with door hardware(e.g., door knob 2504 and strike plate 2200) on the door 2500/frame 2000so that the door 2500 will lock in place in the strike plate 2200 (asthe door will normally be used). When closed arm 300 of apparatus 100can fit within the gap 2050 between the top 2510 of the door 2500 andthe header 2010 of the door frame 2000. The hanging wire 20 also fitsbetween the top 2510 of the door 2500 and the header 2010 of the doorframe 2000 (on the top of the door) and between the rear of the door2500 and the weather stripping 2004 in front of the jam 2006 (althoughnot shown but located at the rear of the door 2500). Arrows 2072schematically indicate that, in one embodiment, arm 300 can be pivotedsomewhat about opening 2020 in header 2010 even when door 2500 is closedin door frame 2000.

FIG. 7 shows a section view of marking apparatus 100 with door 2500closed and force (schematically indicated by arrow 2070) being appliedon marking apparatus 100 with handle 300 while positioning member 500 isin hole 2020 of top door frame 2010 with alarm sensor wire 20 hangingdown on other side of door 2500, and with door 2500 closed. Positioningsurface 530 of positioning member 500 aligns positioning member 500 inthe centerline CL of opening 2020 made in header 2010 of frame 2000.Marking point 550 can also being in the longitudinal centerline CL ofpositioning member 500 causing point 550 to be so aligned withcenterline CL. When door 2500 is closed in frame 2000, pushing down onarm 300 (schematically indicated by arrow 2070) of apparatus 100 (shownin FIG. 39) causes point 550′ to create a mark 2550 in door 2500. Inthis manner, when door 2500 is closed, mark 2550 is also aligned withcenterline CL of opening 2020.

As shown in FIG. 7, wire 20 does not interfere with alignment ofpositioning member 500 because wire 20 can fit in groove 600 whilepositioning surface 530 aligns positioning member in opening 2020. Alsoshown in FIG. 7 arm 300 and marking point 550 of marking apparatus 100can fit within gap 2050 between top 2510 of door 2500 and header 2010 offrame 2000. In some instances the distance between first end 510 ofpositioning member from bottom 304 of arm can be adjusted upwardly inthe direction of arrow 502 (or downwardly in the direction of arrow 504)by rotating positioning member in the direction of arrow 526 (or theopposite direction of arrow 526). As shown in Figure marking point 550of positioning member 500 is generally located in the longitudinalcenterline of opening 2020.

FIGS. 6 and 7 schematically indicate that force in the direction ofarrow 2070 is applied downwardly to the top of apparatus 100 causingmarking point 550 to make a mark, indentation, scratch or scar 2550 onthe top 2510 of the door 2500. To better assist in seeing the mark,indentation, scratch, or scar a different material 2700 can be placed onthe top of the door 2500 (such as painter's tape or masking tape).During this step the front portion 310 of arm 300 is generally in ahorizontal position and located in a horizontal plane between gape 2050.

FIG. 8 shows a point mark 2550 placed on top 2510 of door 2500, and onor through marking material 2700. Generally, two types of marks 2550which can be left by marking point 550 (either a point mark or a scratchline). Point mark is shown, however, although not shown a scratch line2560 ending in a point 2550 can be made where marking point 550 touchesthe top 2510 of the door 2500 when the door 2500 is being closed. Thiscan occur when there is only a small gap 2050 between the top 2510 ofthe door and the header 2010 (i.e., the bottom of the door frame).

FIG. 8 shows a mark 2550 which can be left by marking point 550 whenusing tape 2700. In another embodiment tape 2700 can be omitted.Painter's tape 2700 can be used to better show the mark 2550 made bymarking point 550 (shown in FIG. 7).

After mark 2550 is made in the top 2510 of door 2500, marking apparatus100 can be removed (substantially the opposite procedure is used as thatschematically shown in FIG. 6). A user pushes up (in the oppositedirection of arrow 2070) on the bottom 304 of arm 300 and opens door2500. Door 2500 can be opened and marking apparatus 100 pulled down fromout of opening 2020 of header 2010 (substantially the opposite procedureas shown in FIG. 4). The user pulls out positioning member 500 fromopening 2020 in the header 2010. Wire 20 will then be left hanging fromopening 2020.

In one embodiment (shown in FIG. 1) the positioning member 500 isvertically adjustable relative to the arm 300 to address the situationwhere there are small gaps 2050 and minimize scarring or scratch lines2560. To vertically adjust positioning member 500, positioning member500 can be partially screwed into or unscrewed from arm 300, wherethreads 515 of positioning member 500 will move positioning member 500up or down relative to arm 300.

FIG. 9 shows a 2550 hole being drilled on top 2510 of door 2500 at mark2550 and alarm sensor 14 being placed in the drilled hole 2555. The hole2555 should be the size of the lower sensor 14 to be placed in the door2510 and should be drilled parallel to a vertical plane passing throughthe mark 2550 on the top 2510 of the door 2500. FIG. 9 shows the hole2550 being drilled through the painter's tape 2700. After the hole 2550is drilled the painter's tape 2700 should be removed from door 2500.

FIG. 9 shows the lower sensor 14 being placed in the drilled hole 2555at the top 2510 of the door 2500.

FIG. 10 shows upper 12 and lower 14 alarm sensors in an aligned positionwhen door 2500 is closed in door frame 2100.
